Description

This is my first attempt at an HDR image using PixInsight. It was a little complex and I posted the processing scheme here: https://www.dropbox.com/s/6l373omq9ri0q8c/PIS%20HDR%2011-2019.jpg?dl=0

The new weighted batch preprocessing script in PixInsight was quite helpful. This is about 3.5 hours of Ha, O3, and S2 processed as HSO.
